A displacement control valve V includes a valve housing 10, a valve element 51 constituting a main valve 50 that contacts and separates from a main valve seat 10a, for opening and closing communication between discharge ports 12 and control ports 14 by driving force of a solenoid 80, a pressure-sensitive valve 53 that opens and closes according to ambient pressure, and a pressure-sensitive valve member 52 constituting the pressure-sensitive valve 53 together with a pressure-sensitive element 60. The valve element 51 and the pressure-sensitive valve member 52 are formed with an intermediate communicating passage 55. The intermediate communicating passage 55 allows communication between the control ports 14 and the suction ports 13 by opening and closing of the pressure-sensitive valve 53. The pressure-sensitive valve member 52 is formed with through holes 52d communicating with the intermediate communicating passage 55, and is provided with a sliding member 90 that slides relatively to the pressure-sensitive valve member 52 by fluid flow produced by the opening of the main valve 50, for opening and closing the through holes 52d.

摘要： The present invention not only actively takes fluid into the sliding surface, discharges same from the sliding surface, and prevents concentration of substances that cause sediment on the sliding surface but also prevents leakage of the fluid that has been taken into the sliding surface to the low pressure fluid side while preventing the generation of sediment. The sliding part is characterized in that: one sliding surface of a pair of sliding parts that slide relative to each other is provided with fluid-circulating grooves (10) configured from an inlet (10a) entering from the high pressure fluid side, an outlet (10b) opening out to the high pressure fluid side, and a connecting section (10c) for connecting the inlet (10a) to the outlet (10b); the fluid-circulating grooves (10) are isolated from the low pressure fluid side by land sections (R); and in order to reduce the pressure of the fluid flowing in the fluid-circulating grooves (10) in the connecting sections (10c), the cross-sectional area of the groove at least at the inlet (10a) or the outlet (10b) is set to be different from the cross-sectional area of the groove in the connecting section (10c).
